Description
Technical field
This utility model relates to a kind of split type inlet manifold with interior mixed function, belongs to motor exhaust circular treatment
Field.
Background technology
For air conservation, various countries define particulate matter in motor exhaust, nitrogen oxygen in diesel engine emissions regulations
The limit value of compound.At present, for the continuous upgrading of satisfied country Abgasgesetz, engine assembly commonly used waste gas recirculation skill
Art, to reduce the pollutant emission such as NOx, particulate matter.Exhaust gas recirculatioon technology is to reduce the most effective measure of NOx.And air inlet discrimination
Pipe major function is fresh air, exhaust ventilation (to be carried out EGR valve accurately according to parameters such as the rotating speed of electromotor and loads
Control, to obtain optimal EGR rate) etc. the most uniformly mix and be assigned to each cylinder, for gas stream in this inlet manifold
The length in road should be the most equal.In order to reduce gas flow resistance, improve air inlet ability, the inner wall smooth mistake of inlet manifold
Cross.
In the market, integral type pattern is all used, without special mixing regardless of gasoline engine, diesel engine intake manifold material
Chamber, exhaust ventilation is directly entered inlet manifold, and mixing efficiency is low, poor, it is impossible to realizes accurately controlling, causes certain to complete machine discharge
Impact.
Utility model content
The purpose of this utility model is: the problem existed for above-mentioned prior art, proposes a kind of in existing air inlet system
Hybrid chamber is increased on the basis of system, can be on the basis of saving arrangement space, mixing efficiency significantly improves, and can realize accurately controlling
The split type inlet manifold of the interior mixed function of system.
In order to reach object above, a kind of split type inlet manifold with interior mixed function of the present utility model, including entering
Gas manifold lower body, described inlet manifold lower body is provided with inlet chamber；It is characterized in that: also include be connected fixing with inlet manifold lower body
Inlet manifold upper body；Described inlet manifold upper body includes waste gas inlet, clean air air inlet and hybrid chamber；Described useless
Gas air inlet and clean air air inlet lay respectively at the two ends of inlet manifold upper body；And by after gas inlet channel connection with
Hybrid chamber connects；Described hybrid chamber is made up of the bottom of inlet manifold upper body and the top of inlet manifold lower body；Described hybrid chamber
Connect deviating from clean air inlet port with inlet chamber.
The technical scheme that this utility model limits further as: described inlet manifold upper body and inlet manifold lower body by one
Group bolt fixed installation.
Further, described inlet manifold upper and lower body junction is provided with a circle liner.
The beneficial effects of the utility model: this utility model, in limited engine bin, meets car load and electromotor is total
The structure become is arranged, and the part pipeline of integrated egr system, compact conformation, and installation, maintenance is convenient, saves complete machine cost；Meet
Car load and engine reliability requirement, it is ensured that system stability is reliable；Realize being sufficiently mixed of gas handling system gas, it is provided that accurately control
System, optimizes burning and exhausting.With satisfied burning, emission request.Comparing the non-interior mixed admission manifold of traditional monoblock type, this scheme has
There are the advantages such as compact conformation, volume are little, mixing efficiency is high, special purpose parts is few.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is the structural representation of one embodiment of this utility model.
Fig. 2 is the sectional view of Fig. 1.
Detailed description of the invention
Embodiment one
A kind of split type inlet manifold with interior mixed function of the present embodiment, basic structure as shown in Figure 1-2, including entering
Gas manifold lower body 1 and fix the inlet manifold upper body 2 being connected with inlet manifold lower body, inlet manifold lower body 1 is provided with outlet chamber 1-
1；Inlet manifold upper body 2 includes waste gas inlet 2-1, clean air air inlet 2-2 and hybrid chamber 2-3；Waste gas inlet 2-1
With the two ends that clean air air inlet 2-2 lays respectively at inlet manifold upper body 2；And by gas inlet passage 2-4 connect after with
Hybrid chamber 2-3 connects；Hybrid chamber 2-3 is made up of the bottom of inlet manifold upper body 2 and the top of inlet manifold lower body 1；Hybrid chamber
2-3 and inlet chamber 1-1 connects deviating from clean air air inlet 2-2 end.
Inlet manifold upper body 2 and inlet manifold lower body 1 are fixedly mounted by one group of bolt 3.Inlet manifold upper and lower body connects
Place is provided with a circle liner 4.
Operation principle of the present utility model: in engine operation process, on the one hand fresh air is entered by inlet channel
Enter inlet manifold upper body；On the other hand the waste gas after burning controls through EGR valve to enter in the inlet manifold of the most integrated EGR line
Body, two kinds of gases, under air-intake negative-pressure effect, common enter the hybrid chamber that inlet manifold upper and lower body surrounds, after sufficiently mixing,
Enter back into main airway and be uniformly distributed to each cylinder.
In addition to the implementation, this utility model can also have other embodiments.All employing equivalents or equivalence become
Change the technical scheme of formation, all fall within the protection domain of this utility model requirement.
